Problems solved by technology

Although this compound is hard but very brittle, it will continue to fall off and form continuously during the friction process, which not only corrodes the machine parts, but also consumes additives. The service life of both machinery and lubricating oil is very short.

Abstract

The invention discloses wearing-resistant vehicle lubricating oil which comprises the following raw materials in parts by weight: 20-30 parts of polybutylene synthetic oil, 15-30 parts of corn oil, 8-15 parts of nano diamonds, 1-3 parts of poly-boron amine, 7-11 parts of oxymolybdenum dialkydithiophosphate, 2-6 parts of sodium citrate, 4-9 parts of polyimide, 6-12 parts of modified bentonite, 8-13parts of liquid paraffin, 9-15 parts of pentaerythritol, 5-14 parts of an antioxidant and 3-7 parts of an anti-corrosion anti-rusting agent. The wearing-resistant vehicle lubricating oil is scientific and reasonable in formula, a product made of the lubricating oil is excellent in extreme pressure resistance, high in bearing capability, high in wearing resistance and in addition high in low-temperature flowability, and excellent long-lasting lubrication properties can be achieved.

Description

technical field [0001] The invention belongs to the technical field of lubricating oil, and in particular relates to a wear-resistant vehicle lubricating oil and a preparation method thereof. Background technique [0002] Lubricating oil is an oily liquid coated on the surface of machine bearings. According to its source, it is divided into four categories: animal oil, vegetable oil, petroleum lubricating oil and synthetic lubricating oil. It has the functions of reducing friction, avoiding heat, and preventing machine wear. [0003] The extreme pressure and antiwear agents in traditional lubricating oils are often some sulfur, phosphorus, and chloride compounds. Through boundary lubrication, instantaneous high temperature and high pressure and friction pairs form metal compounds to improve hardness and wear resistance. Although this compound is hard but very brittle, it will continue to fall off and form continuously during the friction process, which not only corrodes the ...
